What type of information do SNPs typically provide in genetic research?

• A. They identify the physical traits of an individual
• B. They are used to trace lineage and ancestry
• C. They give insights into variations that influence disease susceptibility
• D. They exclusively indicate environmental interactions

Answer: (C)

Single nucleotide polymorphisms (SNPs) are the most common type of genetic variation among people. They represent a change in a single nucleotide and are pivotal in understanding genetic influences on diseases. In genetic research, SNPs are crucial as they provide insights into variations in the genome that may influence an individual's susceptibility to various diseases. This connection is invaluable for understanding complex traits and for identifying genetic risk factors that may contribute to health conditions. Research into SNPs allows scientists to study how specific genetic variations correlate with health outcomes, thereby facilitating the development of targeted therapies and personalized medicine approaches. For example, certain SNPs may indicate a higher risk for diseases like diabetes, heart disease, or certain cancers, enabling healthcare professionals to devise more effective prevention strategies or interventions based on a patient’s genetic make-up. The other options, while related to genetics in some capacity, do not encapsulate the primary function of SNPs in research. SNPs do not directly identify physical traits or serve exclusively for tracing lineage; instead, they contribute to understanding the genetic basis of those traits and ancestral connections. Additionally, while environmental interactions can influence health, SNPs themselves are genetic markers and do not exclusively indicate these interactions. Thus, the role of SNPs in elucidating variations
